Biology 2023 JAMB Past Questions - Question 4: The rate of transpiration of a leafy shoot would be highest under
A:
B:
C:
D:
Correct Answer
C
Explanation
The rate of transpiration of a leafy shoot would be highest under conditions of high temperature, low humidity, and strong winds. These conditions create a larger vapor pressure deficit between the inside of the leaf and the surrounding air, facilitating the movement of water from the leaf to the atmosphere through stomata via transpiration. Additionally, ample sunlight stimulates photosynthesis, leading to increased water uptake by the roots, which in turn enhances transpiration rates. Therefore, the optimal conditions for high transpiration rates involve a combination of warmth, low humidity, wind, and sunlight.
